I fixed mine using a vehicle swap. No problems now 👍 I'm lying lol I still got my little shitbox ravioli. I noticed aftermarket pistons from engine tech have full sized oil rings. The toyota "updated" oil rings seem to still consume oil. I figured I'd check around and see what others are using before I order the engine tech rings. I've used enginetech quite a bit in the past. One engine I build using all enginetec parts is a friend I'm still in contact with. She has kept the truck and has so far, as of couple months ago when I brought it up, put 60,000 miles on it. No issues. It's an early 2010s 5.3L chevy truck. As much as I love chevy they have a few issues in stock form. So I'm definitely confident in enginetech brand

[@robertjackson7590]

" The toyota "updated" oil rings seem to still consume oil." I found many of these engines are runnig such a low vac on the PCV System they don't function properly and that's the real problem. Acura/Honda has been running -.2 to -.6inH2O at hot/idle which is too low. Then when you go to Low Tension rings and then to 0-20W oil they developed an oil ring problem. I changed my PCV System to run -1 to -2inHg to correct the problem with a Catch Can. Put a Manometer(30 bucks) on the Dipstick Tube(Hot/Idle) and see if that's the problem. You might be able to correct the PCV System and clear the rings without disassembly. This information off of an F1 site; ---------------------------------------------------------- 5 inHg (2.5psi) crankcase depression is enough to: * eliminate the need for valve stem seals for drag reduction (assumes heads are vented to crankcase) * eliminate the need for oil rings on the pistons (or very weak zero-drag oil rings) * eliminate totally any oil contamination of the combustion chamber (slightest minute trace causes detonation which you must design out or "tune out" with the usual methods that reduce power) * eliminate compression ring flutter and maintain perfect seal at WOT and near-WOT (assuming intake port tuning is somewhat correct) ------------------------------------------------------ This much vacuum will pull too much oil out(in the form of oil mist) of the sump with a production car/truck and is why you won't see it in street cars. F1 are running -17inHg from what I've found. We need again -1 to -3inHg for good function on street applications. kzbin.info/www/bejne/qavHk4uDrdaKlbc

[@Aeyix]

I'm surprised the 10mm single Hex didn't work for the head bolts. That or I'm seriously lucky. In 2019 I had a dealer do a rebuild for me because I was burning coolant. That didn't solve the problem and they pressure tested my head and it was cracked so they replaced that. Fast forward to 2024 and I have a cracked cylinder head again (but I'm doing the repair this time). I actually had to take the head off twice because I forgot to put the plastic water sleeve in the water jacket which unfortunately cost me an extra head gasket and set of head bolts. Each time I had no problem using my 10mm Craftsman Hex Bit socket when breaking and when torquing per spec/procedure. I seriously considered buying the bi-hexagon socket but never once had any sign of slipping or rounding. Amazing video btw! I'm still in the process of my head replacement, just waiting on some parts.

[@luckyme5122]

Great job, young man

[@Eye_4_An_Eye]

if u ever have to do this again or for anyone else...first and foremost NEVER do all pistons at the same time. complete each piston separately so when something goes wrong you know which one is causing the issue. 2nd of all never tip the engine upside down with loose pistons. keep it at an angle so they dont fall out on accident until all 4 are secure in place before torqing. they are aluminum. one dent and all your work is ruined! 3rd of all i noticed you never oiled up the pistons and rings before u plopped the piston in the bore. always oil them first. just a tip from an ex master mechanic. other than that, pretty solid video. good work. putting it back together with no missing bolts is the fun part lol

[@andychips6923]

Outstanding video.. have an 07 scion tc with 290k on the clock and burns a quart every other tank or so. By “burns”, I think it’s the cat burning the oil because it doesn’t smoke at all.. which is weird

[@madhousediy5050]

I am in the middle of this job right now, but not doing the kit. An old toaster oven at 200⁰F makes those wrist pins very easy to just push out without tools. Looking to rebuild my nasty cylinder head as well. It is just so caked with carbon. The valves, springs, and keepers are in an improvised organizer built from a 2 dozen egg carton. 2007 Scion TC.

[@pyronitro]

Great Job! i never had to hammer in a valve seal. normally i use a 10mm long socket and just push a tad and it pops in. this engine design i guess goes across a bunch of toyota engines.

[@benjaminskwirut]

Same. I originally hammered them in, then the last few, I noticed I only needed to push with my finger. So I convinced myself I damaged the others by hammering them so I replaced them all again lol.

[@joefran619]

Great job, especially with not much room to work.

[@tCDragon85]

I like the video. I have to do this to my engine in my Scion tC (which has the same engine). I plan on going with forged internals since I plan on putting a turbo in the car.

[@rainvillecreative5410]

Awesome, replacing the pistons is a good opportunity to reduce the compression ratio a bit so you can run more boost. Also I would suggest 4032 alloy pistons, since 2618 is often overkill and requires larger clearances that cause noise.

[@rx-jailbreaker3472]

if you do go forged look into supra pistons as the bore size for the 2az if 88MM you and have the engine bored out 2mm to fit supra pistions

[@Eye_4_An_Eye]

at 43:09 is EXACTLY what i was talking about below. thats why you NEVER do all 4 at the same time. you put one in first, complete it all the way then you rotate the crank to see if everything is spinning freely. and thats also why you MUST oil everything first. that sandpaper grind you hear is not good at all. you should not be hearing that at all and the pistons should be moving severely easy, gliding like butter. there should be no resistance. if all is good, you move to the next and so on. now you know =]

[@rainvillecreative5410]

@@Eye_4_An_Eye thanks for the info, everything got oiled up and I checked each piston as I went, the way I shot and edited it leaves a lot of these small things out. As for the sliding noise, that's probably from the budget honing job with the flex hone, which I understand is inferior to a professional hone.

[@Eye_4_An_Eye]

@@rainvillecreative5410 nahh brother thats not honing at all thats an issue with the way you did the pistons but i pray all goes well. was a great video but im concerned with how hard it was for you to turn them. it shoudnt be hard like that it should be very easy.

[@michaeldvorak5556]

From what I've heard, the low tension oil rings were the problem with these engines. That and the 10k oil change. Do 3k to 4k oil changes with quality oil to prevent gumming up the rings. I thought that Toyota's upgrade kit (pistons and rings) were not low tension?

[@geoeconomics5629]

When pistons damage cylinder walls at this point will you need new engine block to do this repair properly No doubt you had the bbs to do it

[@isaacdelavega9487]

This repair is simply because the 2azfe rendition toyota had done, caused them to burn oil. They put low tension springs and the pistons weren't meant for them, so this repair has to be done.

[@joserm6823]

Any advice for someone trying to pull this off for the first time and being totally new at this type of things? Granted I have a TC but same engine

[@andychips6923]

Late response.. but, when you’re taking the engine apart document everything.. pictures, notes, etc. Ive always like using the cardboard trick for punching bolts into and then marking on the cardboard with a marker what is what. You can also trace the shape of a surface where bolts go.. very handy. Take your time. Have all the tools, chemicals, work area.. you need ready. Have cups, containers ready for storage trays.. most of this type work is not too complicated.. its all about organization that determines whether it goes smooth or not. O .. and have a back up vehicle ready for parts store trips

[@rogerdale5451]

Look how clean those valves were. Only problem?- low tension rings. Goddamnit!

[@olid.7568]

[@abirsanu]

Toyota sells a complete new short block assembly with all pistons, rings(corrected/revised rings), shafts and all at about $2000 plus minus, some assemblies cost about $1800 with discount, some at about $2300, depends on year and production location. So I'm just thinking what to do in my case as well with my 2008 RAV4 - to go over a rebuild or just buy a new short block assembly from Toyota and reuse my cylinder head with new valves, springs, tappets, chain and all the stuff.

[@rainvillecreative5410]

If you're doing the work yourself, might as well do it all on your own. Having a complete short block will only save you a small amount of time. You'll still have to pull the engine, swap all the stuff, refresh the cylinder head, etc.

[@glenglene8473]

do you think you have too much rotational play on the two-gear balance shaft? When it's new, you can hardly rotate the gear, but I can see you're able to rotate the gear almost a tooth. Do you detect clattering noise when step on or let go of the gas pedal?

[@rainvillecreative5410]

You might be on to something... there is low RPM clattering that I had assumed to be piston slap. It's mostly at idle, but goes away quickly when RPMs go over 1000. I thought it might be a timing chain issue too maybe. I will look into this more.

[@glenglene8473]

@@rainvillecreative5410 if you detect clattering noise (similar to ticking) at idle and around the head vicinity and noise seems to fade away as speed increases, it's likely due to the two-gear balancer out of synchronization due to too much rotational play. When it has too much play, the fibrous gear (black gear) teeth eventual break into small pieces and clog up the oil pickup causing oil starvation.

Great job there! Did you have to remove the cv axle on the passenger side in order to have room to separate the engine from the the tc/tranny?

[@rainvillecreative5410]

I don't think so, but I would recommend it. The driveshaft on the back of the engine that the passenger CV axle connects to is what gets in the way, not the CV axle itself. It has to be unbolted but it would help to fully remove the shaft since I remember it getting in the way of the block, mostly with putting the engine back in though.

what's usually the most common fail on this engine's?

[@pkey7370]

toyota admitted their fault was the piston rings. They released a kit which once its done it can probably give you a great mileage. You can check if yours has had it done by checking the color of the Sealant used. If its grey, thats factory. If its black, that means someone else has been inside. If the timing cover, the top cover and bottom cover show all black, its likely someone opened up the engine for a rebuilt and could of been done already.

They're kind of sub-par for a modern 2.4 engine, in that they are so-so fuel consumption-wise, and aren't particularly spritely in the performance department. Add to that the oil consumption, and why bother. My freaking worn-out PT Cruiser uses less oil than my friend's RAV4 that just got towed to the shop, and I think her car is doomed. POS. I'm told that rebuilding these things is a fool's errand. A new short-block is the only practical solution. The old 5SFE 2.2 Camry engine was amazing - unless seriously overheated. Got 400K out of one before I killed it with a heavy trailer on a long hill. Still got me home, and ran and drove for a couple more weeks before I traded it in. Oil light on the whole time, and knocking like a bastard. I miss that ugly old wagon.

[@rainvillecreative5410]

I think it's an OK engine at best, but not a POS. The work did eradicate the oil burning, though, so I consider it a success. Might just be from clean, fresh rings, who knows, but if it starts burning oil again at 300k miles, who cares. I just rebuilt a K24 and the differences between that "amazing" engine with large aftermarket support and this "junk" 2AZ are small.
